Mercedes-Benz ECO Start/Stop Mode Shut Down

Posted on by

Mercedes Benz has determined that certain 2016-2017 GLE43 & GLE43 Coupe vehicles may have engine control unit (ECU) software that is incompatible with the transmission control unit programming.

An engine shutdown could also result following a slight tap of the accelerator pedal after a combination of an ECO start and a simultaneous high engine load. The instrument cluster warning lamps will be activated upon engine shut down with and ignition “ON”, indicating to the driver that the vehicle is not in ECO start/stop mode and needs to be restarted manually.

Dealers will correct the problem by reprogramming the engine and transmission control unit software. Owners wanting more information about the problem are asked to contact MBUSA customer service at 1-877-496-3691. The NHTSA campaign number for this recall is 17V-506.
